This works if you're not using J2EE session variables, although
personally I would explicitly check for CFID and CFTOKEN as the key
names. They will not change between versions, as they're so entrenched
in all versions of ColdFusion, and you remove the possibility of a
developer naming a session variable "CFMYVAR" or something. I would
also add in a check to preserve SESSIONID and URLTOKEN as well in the
event that you switch to J2EE session variables. So a re-factored code
snippet might look like:
for ( i in session ) {
if ( not listFindNoCase("CFID,CFTOKEN,SESSIONID,URLTOKEN", i) ) {
// Safe to delete since it's not a built-in CF variable
structDelete(session, i);
}
}
